Sample preparation method and Laboratory sampling procedures involve either: Coning and Quartering; or Riffling Method. Coning and Quartering for sample preparation techniques/method The method which is used for sampling large quantities of material say 20kg, consists of pouring or forming the material into a conical heap upon a solid surface (e.g. a .
For determination of the silica content of respirable coal mine dust samples, the Mine Safety and Health Administration (MSHA) employs the MSHA P7 Infrared Method, hereafter referred to as P7 [10,11]. The MSHA and NIOSH IR methods are similar but with some differences noted in the sample preparation. Airborne dust samples from

these, however, only kaolinite has been detected in coal mine dust. MSHAP-7 1.6.1.1. Coal mine dust frequently contains kaolinite. Since kaolinite has an absorption band at the same wave number as quartz (~800 cm-1), its presence causes an overestimation of the quartz mass. However, kaolinite also has an infrared absorbance band at~ 915
Sample Preparation Equipment is oriented toward smaller scale particle size reduction and sample division activities that are commonly associated with laboratory activities.
